The bug in question is "SDL/OpenGL: Crash when switching renderer backend". To
fix it I added a stupid graphics state copying to the SDL backend, in case the
graphics manager is switched. The implementation of this is considered a pure
workaround, no one should ever do it like this in reality... I just want to
die when looking at this... Not sure why I actually committed it.
Anyway it at least makes the OpenGL backend testable for those who do not
want to fiddle with the config file directly.
This gets rid of the hacks, where SdlEventSource added events with custom type
numbers to pass SDL_VIDEOEXPOSE and SDL_VIDEORESIZE to the graphics manager.
Furthermore it get rids of the uninituitive and hard to trace way of assigning
the proper mouse coordinates to mouse related events. Formerly it passed the
real screen coordinates through the even dispatching api to the graphics
manager (at least hopefully ;-) and let that handle creating a new event with
the proper coordinates. Now instead SdlEventSource handles the proper
coordinate setup itself.
Since this is a behavior change and I can not test all the SDL based small
devices ports this commit might break compilation for them and more serve it
might also break mouse position behavior. If any of that occurs I am sorry
about it.
This tries to make our code a bit more compliant with our code formatting
conventions. For future use, this is the command I used:
git ls-files "*.cpp" "*.h" | xargs sed -i -e 's/[ \t]*$//'
